Honest question. Do you think the GNOME project is as healthy today as it was, say, 4 years ago? Benjamin Otte explains that no, it isn't. GNOME lacks developers, goals, mindshare and users. The situation as he describes it, is a lot more dire than I personally thought.

Gnome manages to barely survive because of "forks" like Mate and Cinnamon. That is probably why Mint is ATM the most loved distro.
I have always hated KDE 4 with a passion since 4.0, while I used to find KDE 3 the best destop out there, bare none.
Nowadays I use OS X 90% of the time, but it has its problems too.
